You did not mention what you have on your rifle for a Scope, or what power it is.
Also no mention of what Trigger you have in it either.
Also what you have for scope mounts. To include how they attach to the Rail.
What Handguard are you using?
All the above make a difference in Group Size.
When I am doing Load Development on something new, I like to start out with a scope of at least 20X so that I can see well enough to shoot Small Groups. I go to a lot of trouble making sure that the Scope is as perfectly straight up and down as possible. On an AR, which is normally not real front sand bag friendly, I will use a Harris Bipod for a front rest, and a rear sand bag under the butt. As mentioned above the Trigger is also important in shooting groups. I have JP, Jewel, and Stern Defense Triggers. I also have a couple with Bone Stock Triggers that are both way better than normal, or I would have replaced them.
grayfox mentioned 50-100 rounds could be required to break in the barrel. You need to do a lot of cleaning during barrel break in. I normally consider 50 rounds with a cleaning every 5 Rounds to be pretty much where I start cleaning after each Range Trip.
After seeing what the rifle is capable of doing, you can switch back to your every day carry optical sight.
You mentioned that you reload. I am amazed that you did not start out shooting your own custom loads. I have several rifles that have never had a factory round fired in them.
Reloading I like the 120-123 ELD-M 6.5 Bullets fairly well.
You should have a powder on hand that the 6.5 Grendel will like reasonably well.
Start working up loads and see what it will do.
